  • How to extend a file definition from an existing module in the node?

    - by c33s
    I use an older version of the example42 mysql module, which defines the mysql.conf file but not its content. Mmy goal is to just include the mysql module and add a content definition in the node. class mysql { ... file { "mysql.conf": path => "${mysql::params::configfile}", mode => "${mysql::params::configfile_mode}", owner => "${mysql::params::configfile_owner}", group => "${mysql::params::configfile_group}", ensure => present, require => Package["mysql"], notify => Service["mysql"], } ... } node xyz { include mysql File["mysql.conf"] { content => template("mymodule/mysql.conf.erb")} } The above code produces a "Only subclasses can override parameters" What is the correct way to just add a content definition to an existing file definition?

  • oracle call stored procedure inside select

    - by CC
    Hi everybody. I'm working on a query (a SELECT) and I need to insert the result of this one in a table. Before doing the insert I have some checking to do, and if all columns are valid, I will do the insert. The checking is done in a stored procedure. The same procedure is used somewhere else too. So I'm thinking using the same procedure to do my checks. The procedure does the checkings and insert the values is all OK. I tryied to call the procedure inside my SELECT but it does not works. SELECT field1, field2, myproc(field1, field2) from MYTABLE. This kind of code does not works. I think it can be done using a cursor, but I would like to avoid the cursors. I'm looking for the easiest solution. Anybody, any idea ? Thanks alot. C.C.

I have no idea how to use MAX() on joins.

  • SQL Server insert performance with and without primary key

    - by Eric
    Summary: I have a table populated via the following: insert into the_table (...) select ... from some_other_table Running the above query with no primary key on the_table is ~15x faster than running it with a primary key, and I don't understand why. The details: I think this is best explained through code examples. I have a table: create table the_table ( a int not null, b smallint not null, c tinyint not null ); If I add a primary key, this insert query is terribly slow: alter table the_table add constraint PK_the_table primary key(a, b); -- Inserting ~880,000 rows insert into the_table (a,b,c) select a,b,c from some_view; Without the primary key, the same insert query is about 15x faster. However, after populating the_table without a primary key, I can add the primary key constraint and that only takes a few seconds. This one really makes no sense to me. More info: The estimated execution plan shows 0% total query time spent on the clustered index insert SQL Server 2008 R2 Developer edition, 10.50.1600 Any ideas?

  • Insert methode of TableAdapter not working?

    - by Stijn Leenknegt
    I'm using ADO.NET in my C# project. In my form I added a SourceBinding element from my toolbox in VS2010. I set the connection to the table of my dataset. It creates a DataAdapter automaticly for my. I want to insert a record, so I call the Insert() method of the DataAdapter. But when I view my database data, it doesn't have any new records... orderID = this.orderTableAdapter.Insert("", "", (int)OrderStatus.IN_CONSTRUCTION, DateTime.Now); Or do I need to insert it manually with the SqlCommand???

  • Which is more efficient in mysql, a big join or multiple queries of single table?

    - by Tom Greenpoint
    I have a mysql database like this Post – 500,000 rows (Postid,Userid) Photo – 200,000 rows (Photoid,Postid) About 50,000 posts have photos, average 4 each, most posts do not have photos. I need to get a feed of all posts with photos for a userid, average 50 posts each. Which approach would be more efficient? 1: Big Join select * from post left join photo on post.postid=photo.postid where post.userid=123 2: Multiple queries select * from post where userid=123 while (loop through rows) { select * from photo where postid=row[postid] }

  • PHP - get MySQL query results as their native data type?

    - by redidas
    I've tried fetching MySQL query results using mysql_fetch_row() mysql_result() and numeric values are being returned as strings.

The application will be querying many different queries so I will be unable to cast the values as the intended datatype on a 1 by 1 basis.

  • Can I restore a single table from a full mysql mysqldump file?

    - by Mobius
    I have a mysqldump backup of my mysql database consisting of all of our tables which is about 440 megs. I want to restore the contents of just one of the tables form the mysqldump. Is this possible? Theoretically, I could just cut out the section that rebuilds the table I want but I don't even know how to effectively edit a text document that size.

  • How should i store availability calendar information in mysql? for [id] [date] [available/unavailab

    - by Haroldo
    I'm building a simple calendar for holiday cottages to show when they are booked or available. What would be the fastest mysql table design for this, bearing in mind when users mark dates as available/booked they will do so via a start date and an end date. i can see 2 obvious options Store 'booked' data for every day [more rows] or, store 'booked' data with 2 columns a start_date and end_date [more processing?] Which is best or is there another method i'm missing?
